The aerospace industry is beginning to grapple with the reality of certifying
electric aircraft (EA), signaling the maturing of the field. Many players are
ramping up their activities to respond to imminent technical, safety, and
regulatory requirements. While there are gaps in EA knowledge as well as the
processes for certifying them, some leading standards development organizations
(SDOs) such as SAE International, ASTM International, and RTCA—ably supported by
representatives from regulatory agencies—are stepping in to address many of
these issues.
Of special importance are the new rule changes in the normal category (14 CFR
Part 23, Amendment 64) that shift from a prescriptive philosophy to
“performance-based rules.” Regarding system knowledge, there has been a trend in
the use electrical energy to power systems that have long employed mechanical
hydraulics. In the new EA paradigm, these components will be employed at
criticality levels not previously witnessed in conventional aircraft, calling
for a specific set of certification demands.
Unsettled Issues Regarding the Certification of Electric Aircraft
tackles the certification challenges faced by EA manufacturers in both the small
(normal) and large (transport) categories, addressing technical, business, and
process issues.
